Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules.

This standard replaces GB/T 3789.1-1991 ~ GB/T 3789.31-1991 "emission tube electrical performance test methods." this standard and GB/T 3789.1-1991 ~ GB/T 3789.31-1991 main changes are as follows.

--- This standard GB/T 3789.1-1991 ~ GB/T 3789.31-1991 in "launching tubes electrical performance test methods - General" and 30 standard test method for the integration of a standard;

--- Increased testing methods triode anode ion current (see 10.1);

--- Delete duplicate and GB/T 4597 "tube vocabulary" in the term;

--- Remove the GB/T 3789.11-1991 "test the electrical properties of transmitting tubes - Test method of the third gate-off voltage" and GB/T 3789.23-1991 "emission control testing methods of the electrical properties of the third gate control" is not applicable content;

--- The GB/T 3789.4-1991, GB/T 3789.5-1991, GB/T 3789.6-1991, GB/T 3789.8-1991 and Electrical principles GB/T 3789.14-1991 in pentode tetrode circuit diagram to FIG.

3 Terms and Definitions

GB/T 4597 and GB/T 2987 defined by the following terms and definitions apply to this document.

Static characteristic curve Under the provisions of the operation, the relevant parameter has only one characteristic curve (parametric relationship between the two) DC values.

Anode characteristic curve platecharacteristiccurve when the remaining electrode voltage holding value, a first gate voltage takes a certain value, and the anode current versus anode voltage (a first gate electrode Anode current versus voltage and anode voltage for different values \u200b\u200bof the composition of the characteristic curve family).

Anode - the first gate characteristic plate-gridNo.1characteristiccurve Setting remaining voltage holding electrode, the anode voltage takes a certain value, and the first anode current versus gate voltage (anode voltage takes Anode current versus gate voltage different from the first value when the composition of the characteristic curve family).
